Porsche designs 500ps production 911 GT3 R

OEM reveals that the new customer sports racer is powered by 4-liter flat-six engine

 

Based on the 911 GT3 RS production sports car, Porsche has designed a customer sport race car for GT3 series around the world – the 911 GT3 R, a car capable of producing more than 500ps.

Powering the new 911 GT3 R is a 4-liter flat-six unit, which is largely identical to the high-performance production engine of the road-legal 911 GT3 RS. Direct petrol injection, which operates at pressures up to 200 bar, as well as variable valve timing technology ensure a particularly efficient use of fuel. Moreover, the normally-aspirated engine offers significantly better driveability and a broader usable rev range. Power from the rear engine is transferred to the rear wheels via a Porsche sequential 6-speed constant-mesh gearbox. As in the GT road-going models of the 911, the driver changes gears via shift paddles on the steering wheel.

The water-cooled six-cylinder boxer engine is mounted at the rear, and features bore of 102mm and stroke of 81.5mm. The output is subject to FIA BoP (air restrictor). You can see, and hear, more of the new GT3 R in the video clip below.
